You may use a protective facemask.  Follow the instructions that came with the mask.

• Place the victim on his or her back.

• Press your palm against the person's forehead. At the same time hook your fingers under the chin and lift it away from the spine, as if pulling out a drawer. This tilts the head back and opens the airway. 

• If there is a possibility of a broken neck, place the victim on his or her back without moving the neck or chin.

• Check to see if the chest is rising.

• Listen for normal breathing (not gasping for air).

• If there is no normal breathing, start mouth-to-mouth breathing as described in Steps 3 to 5.

• Adults and children (age 1 to puberty):

  • Keep the head tilted back and chin down.

  • Pinch the victim's nostrils together with your thumb and first finger. Or follow your facemask instructions.

  • If you don't have a protective barrier, seal your lips over the victims open mouth. 

  • Note: If the victim's mouth can't be opened, you can seal your lips over the victim's nose.

• Infants (up to age 1):

  • Cover the infant's nose and mouth with your mouth or a protective barrier. 

• Adults and children (age 1 to puberty):

  • Breathe into the victim's mouth for 1 second. Watch for the chest to rise.

  • If the chest rises, breathe into the victim's mouth a second time.

  • If the chest doesn't rise, tilt the victim's head back and chin down again. Then breathe into the victim's mouth a second time.

• Infant (up to age 1):

  • Give 2 gentle puffs or breaths of air instead of a deep breath. Each puff is given 2 seconds apart because each gentle breath should last 1 second.

  • If the chest rises, breathe a gentle puff or breathe into the victim's mouth a second time.

  • If the chest doesn't rise, tilt the victim's head back and chin down again. Then breathe into the victim's mouth a second time.

  • If the chest still doesn't rise, check inside the mouth for a foreign object after chest compressions. If an object is visible, sweep the mouth with your fingers and remove the object. Take care not to push the object further into the throat.

• Adults and children (ages 1 to puberty):

  • Give 2 breaths after 30 chest compressions until the person starts breathing or emergency medical services arrive. Push fast, at least 100 to 120 continuous compressions per minute. Give one breath every 6 seconds (10 breaths//minute).

• Infants (up to age 1):

  • Give 2 breaths after 30 chest compressions until the infant starts breathing or emergency medical services arrive. Push fast, at least 100 to 120 continuous compressions per minute. Give one breath every 6 seconds (10 breaths//minute).

It is best to be prepared in the event of an emergency. Look for classes offered by your local hospital, the American Heart Association, or the American Red Cross in your area or on the Internet.
